This is a popular art form unique to the Nairiku Line, with rice fields along the route. Rice field art displays are created every year at five locations: between Kakunodate Station and Ugo-Ota Station, at Kami-Hinokinai Station, between Aniai Station and Kobuchi Station, between Maeda-Minami Station and Ani-Maeda-Onsen Station, and at Jomon Ogata Station. As the seedlings grow from July to September, they are designed in such a way that a large picture appears to emerge, providing onlookers with a surprisingly massive work of art.
